Abstract

Palladium acetate (5 mol%) effects catalytic inter-and intra-molecular coupling of vinyl bromides in good yield under mild conditions provided sufficient triarylphosphine and potassium carbonate are present to regenerate the active palladium (O) species. Wilkinson's catalyst is a poor catalyst for the same coupling reaction. Double bond isomerisation is not observed under these conditions. The palladium catalyst also couples iodobenzene to ...
